具有长烷基链的衍生化卟啉，5，10，15，20-四（十六烷氧基苯基）-21H，23 H-卟啉，在推测的非共价相互作用中对半导体单壁碳纳米管（SWNT）具有选择性，根据拉曼、近红外吸收和体电导率表征，导致溶解的样品中显著富集半导体SWNT，并且残余固体样品中主要是金属SWNT。
A derivatized porphyrin with long alkyl chains, 5,10,15,20-tetrakis(hexadecyloxyphenyl)-21H,23H-porphine, is selective toward semiconducting single-walled carbon nanotubes (SWNTs) in presumably noncovalent interactions, resulting in significantly enriched semiconducting SWNTs in the solubilized sample and predominantly metallic SWNTs in the residual solid sample according to Raman, near-IR absorption, and bulk conductivity characterizations.
